• Perl
  
  You can also get Perl from the Debian project, here. Be sure to get the "*_arm.deb" packages (e.g., "perl-base_5.6.1-7_arm.deb" and "perl_5.6.1-7-arm.deb").
  
  Then open the and use the command "dpkg-deb -xX ..._arm.deb" to unpack it. It will end up in a "DEBIAN" directory. Use the Unix "mv" to move the files (...) and create symlinks, if needed.

• Don't call qApp->quit()
  
  In your C++ source, make sure that you simply close the window for your application, rather than quitting it completely with "qApp->quit();". You should also call "showMainWidget()" on the QPEApplication instance, rather than on the QApplication-inherited "setMainWidget()".
